Donegal East was a parliamentary constituency represented in Dáil Éireann, the lower house of the Irish parliament or Oireachtas from 1937 to 1961. The constituency elected 4 deputies (Teachtaí Dála, commonly known as TDs) to the Dáil, on the system of proportional representation by means of the single transferable vote (PR-STV).
The constituency was created under the Electoral (Revision of Constituencies) Act 1935, for the 1937 general election to Dáil Éireann.[1] It succeeded the constituency of Donegal. It was abolished under the Electoral (Amendment) Act 1961, when it and Donegal West were replaced by the new constituencies of Donegal North-East and Donegal South-West.
It consisted of the administrative county of Donegal except the portion thereof which was comprised in the county constituency of Donegal West.[1]
Following the death of Fianna Fáil TD Neal Blaney, a by-election was held on 7 December 1948. The seat was won by the Fianna Fáil candidate Neil Blaney, son of the deceased TD.
